Description

Technical Field

[0001] This utility model relates to the field of oral implant technology, specifically to a bone graft filling device for oral implant surgery. Background Technology

[0002] Dental implantology is a type of dental prosthesis that uses implant-supported prostheses. Implant prostheses are supported by artificial implants placed into the jawbone, reducing or eliminating the need for a denture base and increasing patient comfort. For patients with severe alveolar bone atrophy, implants need to be fixed to the alveolar bone. However, due to varying patient conditions, some patients have insufficient alveolar bone depth after atrophy, resulting in exposed cavities around the implant. In such cases, prepared bone grafting is needed to fill these cavities to ensure the stability of the implant after placement.

[0003] Traditional bone powder filling devices are made of needle tubes, which makes it difficult to control the amount of bone powder filled according to the alveolar bone depth during the filling process, resulting in overfilling and greatly affecting the bone powder filling effect. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the above-mentioned technical difficulties and provide a bone powder filling device for oral implant surgery, which can quantitatively fill bone powder, prevent overfilling, and greatly improve filling efficiency.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a bone powder filling device for oral implant surgery, including a bone powder filling cylinder, a detachable injection cylinder at the upper end of the bone powder filling cylinder, a filling port at the lower end of the bone powder filling cylinder, a push rod slidably inserted into the injection cylinder, a push piston slidably connected to the lower end of the push rod and the push plate fixedly connected to the upper end of the push rod; a metering cylinder fixedly connected to one side of the injection cylinder, a metering rod extending into the metering cylinder fixedly connected to one side of the push plate, a positioning slider fixedly connected to one end of the metering rod extending into the metering cylinder, a metering stop slidably connected to the metering cylinder, a fixing bolt threadedly connected to the metering stop, sliding holes that cooperate with the fixing bolts on both sides of the metering cylinder, and a positioning block fixedly connected to one end of the fixing bolt extending out of the sliding hole.

[0006] As an improvement, the lower end of the injection cylinder is fixedly connected to an external threaded connecting cylinder, and the upper end of the bone powder filling cylinder is provided with an internal threaded connecting port that mates with the external threaded connecting cylinder.

[0007] As an improvement, the outer wall of the metering cylinder is provided with graduation lines.

[0008] As an improvement, both the positioning slider and the positioning stop are fixedly connected to a semi-circular positioning ring that is slidably connected to the outer wall of the metering cylinder.

[0009] As an improvement, a sealing plug is fitted onto the lower end of the filling port.

[0010] As an improvement, the upper end of the syringe is fixedly connected with corresponding finger rings arranged on both sides.

[0011] The advantages of this invention compared to existing technologies are as follows: By adjusting the positioning stop blocks to slide up and down along the inner wall of the positioning cylinder, the distance from the positioning slider can be adjusted. After adjustment, the fixing bolts on both sides are tightened so that the positioning blocks on both sides abut against the outer wall of the positioning cylinder. When the push plate is pressed, it drives the push rod to guide the material downward. The push rod drives the metering rod to slide downward. When the metering slider contacts the metering stop block, the maximum filling amount is obtained, preventing overfilling and greatly improving filling efficiency. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1 to 5As shown, a bone powder filling device for oral implant surgery includes a bone powder filling cylinder 1. The upper end of the bone powder filling cylinder 1 is provided with a detachable injection cylinder 2. The lower end of the injection cylinder 2 is fixedly connected to an external threaded connecting cylinder. The upper end of the bone powder filling cylinder 1 is provided with an internal threaded connecting port that mates with the external threaded connecting cylinder. The upper end of the injection cylinder 2 is fixedly connected with corresponding finger rings 13 on both sides. The lower end of the bone powder filling cylinder 1 is provided with a filling port, and a sealing plug 15 is sleeved on the lower end of the filling port.

[0020] A push rod 3 is slidably inserted into the injection cylinder 2. The lower end of the push rod 3 is fixedly connected to a pusher piston 4 that is slidably connected to the bone powder filling cylinder 1. The upper end of the push rod 3 is fixedly connected to a push plate 5. A metering cylinder 7 is fixedly connected to one side of the injection cylinder 2. The outer wall of the metering cylinder 7 is provided with a scale line 8, which matches the capacity of the bone powder filling cylinder 1. A metering rod 6 extending into the metering cylinder 7 is fixedly connected to one side of the push plate 5. A positioning slider is fixedly connected to one end of the metering rod 6 that extends into the metering cylinder 7. A metering stop 10 is slidably connected inside the metering cylinder 7. A semi-circular positioning ring 14 that is slidably connected to the outer wall of the metering cylinder 7 is fixedly connected to both the positioning slider and the positioning stop. The scale line 8 can be observed more clearly through the semi-circular positioning ring 14. A fixing bolt 11 is threadedly connected to the metering stop 10. Sliding holes 12 that cooperate with the fixing bolt 11 are provided on both sides of the metering cylinder 7. A positioning block is fixedly connected to one end of the fixing bolt 11 that extends out of the sliding hole 12.

[0021] In practical use, screw the bone powder filling cylinder 1 to separate it from the injection cylinder 2. After filling the bone powder into the bone powder filling cylinder 1, thread the injection cylinder 2 back into the bone powder filling cylinder 1. Alternatively, fill the bone powder directly from the filling port. Push the push plate 5 to drive the push rod 3 and the push piston 4 to slide downwards along the inner wall of the metering sleeve, allowing the bone powder to be input into the filling port and compacting the bone powder in the bone powder filling cylinder 1. Push the positioning blocks on both sides to drive the positioning stops to slide up and down, and observe the scale line 8. Adjust the positioning stops accordingly. Adjust the block to the appropriate position and tighten the fixing bolts 11 on both sides so that the positioning blocks on both sides abut against the outer wall of the metering cylinder 7. When it is necessary to fill bone powder, remove the sealing plug 15, place the filling port at the position where bone powder needs to be filled, push the push plate 5 to drive the push rod 3 and the push piston 4 to slide downward, and push the bone powder out from the filling port. At the same time as the push plate 5 slides downward, it drives the metering rod 6 to push the metering slider 9 to slide downward. When the metering slider 9 abuts against the upper end of the metering stop 10, the maximum filling amount is reached to prevent the filling amount from being too large.
